Automated pre-dimensioning of shaftbearing-systems for electrified vehicle transmissionsopic

Topic and Goal of the Thesis

The electrification of heavy commercial vehicles is a core aspect to CO2-reduction. Switching to electrified powertrains means however additional challenges in the vehicle development process. One way for mastering the complexity of a powertrain development is to incorporate various designing tools directly into the process.

For the further development of existing tools, an approach for automated shaft design for spur gearboxes shall be worked out. The method should be implemented as an extensible interface between synthesis of transmission topology and gear simulation with a focus on electrified propulsion systems. In conclusion, an exemplary comparison of the automatically created design and a gearbox for an electrified vehicle is rounding off the method proposed in the thesis.

Working Points

  • Research on the state of the art of shaft and bearing calculation
  • Development of a corresponding methodological approach
  • Implementation of the methodology in MATLAB
  • Approach application using a gearbox topology similar to the series-production ones and design visualising


  • Interest in the vehicle transmission development
  • Good English or German language skills
  • Reliability, commitment and enjoyment of working independently

Note: Please attach brief resume and grade summary.
